CAR-HEATER AND `PIPE-CONNECTION.

SFECIFICATION forming part of Letters Patent No. 417,447, dated December 1*?, 1889.

Application iled May 20, 1889. Serial No. 314,412. (No model.)

To all whom it may concern:

Be it known that I, EGRERT PERRY SARTELL,

of St. .C1oud, 4in the county of Stearns and .State of Minnesota, have invented certain new and usefullmprovements in Car-Heaters and Pipe-Connections; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it .appertains to make and use the same, reference being had to the accompanying drawstituted therefor, having improved coupling or connecting heads on theirends, said pipes being capable of lateral, vertical, and longitudinal play; and a further object is to so inclose said pipes and couplings that the heat radiated therefrom will not be wasted, but conveyed back into the car. These objects are accomplished by, and my invention consists in, certain novel features of construction and in combinations of parts more fully described hereinafter, and particularly pointed out in the claims.

Referring to the accompanying drawings, Figure l is a detached plan View of the interior ofthe box or chamber attached to one end of a car. Fig.A 2 is avertical longitudinal section of the device of Fig. l. Fig. 3 is a View, similar to Fig. 2,0f a modification. Fig.

, ais alongitudinal section of a pair of connecting-heads about to engage, the valves in the same being shown opened to avoid confusion of parts, as if the heads were in tight engagement. Fig. 5 is a detail perspective of'a coupling-head. Figs. 6 and 7 are details.y

` In the drawings the reference-letter a indicates the steam or hot-air or other heating pipes. Two are shown in the present instance extending into and through the car and downopposite ends into boxes or chambers b, secured to the bottom of the carat the opposite ends thereof and projecting forwardly from said ends. The heating pipe or pipes extend horizontally and longitudinally through said Aboxes and project from the front ends of the same beyond the end of the car. On its projecting end each, pipe is provided with the half member of a pipe-coupling, each coupling head or member consisting of an outwardly-Haring head c, secured to the end of its respective pipe. The end of the head is proedge of the head around said recess is provided With the elast-ic packing-ring c, secured in a groove in said edge. This recess d is partially filled by a semi-spherical Ablock f, secured or formed therein at an angle, with one side or edge projecting therefrom, so thatthe fiat inner face g of the semi-sphere will be located in said recess at an angle, leaving acorresponding recess or socket beside it. This inner face is provided with one or more annular packing-rings secured thereon and surrounding a central port h, communicating with the interior of the heating-pipe by passage t', extending through the iiaring head. A hinged check-valve j is located in said head to close said port by the back-pressure when the connection or coupling is released, and the valves of a pair of connecting or coupling members are automatically opened,when coming togetheiyby means of arms or a hinged ring k, located at the exterior of the port and connected with the valve, so that when the two heads come in contact the hinged rings or arms will force back the valves and open the ports.

From the foregoing it will be readily seen that when the connection is made the surrounding edges of the two flaring heads tightly engage with the fiat inclined faces g and their packing-rings in contact and with the ports therein registering, and the projecting ends of the blocks f fitting'snugly in the recesses beside the faces g of the opposite member, thereby forming a perfect and tight compound joint, as the inner joint between the faces g g is within and at an angle wardly through the bottom of the car at its vided with a sei'ni-spherical recess d, and the to and crossing the plane of the outer surrounding joint between the edges of the flaring heads, and the projecting portion of each member fitting into the corresponding socket of the opposite member prevents independent vslipping or play at the joint. The tighter the cars are coupled the closer will be the connection, as the connection is made by the abutting car. 1

The horizontal portions a of the heatingpipes a in the chambers b and carrying the coupling-heads are connected with the pipes in the carby the vertical portions and elbows land the coupling-elbows l', in the outer ends of which ythe inner ends of said pipe-sections a. loosely extend, so as to be longitudinally movable therein and to receive packing to form a tight joint therewith, and the coupling-heads are yieldingly held to their limit of outward movement bythe coiled splings m, interposed between and securely fastened to the lugs or projections n on the pipe-sections a and stationary lugs n in the chamber. These springs hold the coupling-heads yielding and yet tightly together when the coupling is made.

A box or casing o surrounds the pipe-sections carrying the coupling-heads, which sections pass through apertures in the ends of the box, and the two coupling-heads at each end of the car are thereby held against independent lateral or vertical movement. The top and bottom of this box is provided with guides or tracks j), against which the blocks q on the pipesbear and move when the pipes are moved longitudinally, and this box is yieldingly held in position to allow lateral and vertical play of the coupling-heads by coiled springs r, interposed loosely between plates s, bearing against the sides and top and bottom of the box o, and corresponding adjustable plates t, located at the top and bottom and sides of the chamber b, said plates bearing against set-screws w, by which the tension of the springs r can be varied; the side plates t adapted to move in ways, as shown, the connections between the pipesections carrying the coupling-heads, and the main pipes in the car being formed by coupling sleeves and joints, so as to allow the pipe-sections universal and also longitudinal play, as described, against the tension of the springs, which yield to the motion of the car.

The front ends of the chambers b are provided with supplemental ends or flexible spring-bumpers c', provided with openings which register with openings in the front ends of the chambers b, for the passage of the coupling-heads and pipes carrying the same, and these bumpers are loosely secured to the ends of said chambers by flexible sides or casings d', and are yieldingly held at their limit of outward movement by the expansible springs e', preferably secured to plates attached to the ends of the chambers and the supplemental ends. The face of each bumper and the opening therein is surrounded by the packing f. Thus it will be seen that when two cars come together and are coupled the bumpers c engage and are compressed, and the pipes are automatically connected and coupled and communication established between the interiors of the two chambers b, which interiors are sluit out of communication with the outer air by the fiexible bumpers c and packing f', and hence all the heat radiating from the coupling and pipes outside of the car will be retained and passed into the car through the openings and registers.

In Fig. 3 a modification is shown, in which but one large coil-spring tapering toward the ends is used, embracing the pipes and bearing against the plates t, and the ends of the spring are secured to surround four plates h', (see Fig. 6,) each plate having two apertures through which the pipes extend, and each pair of plates are rigidly secured together, clamping blocks ornuts i', secured to the pipes rigidly between the same. (See Fig. 7.) These nuts are tightly clamped 011 the pipe-section to prevent the same from turning or partially rotating. A casing o surrounds the pipes within this spring. This coil-spring is secured to the plates t by adjustable staples t', passing through the plates and the walls of the chambers b.

Vertical coiled springs s s are located and securely fastened between the plates h and the bottom plate t to assist in sustaining the weight of the pipes d and their attachments.

The device is shown and described as having two pipes and coupling-heads at each end of the car, the pipes being connected with radiators on opposite sides of the car, although it is evident that if desirable one pipe and coupling only need be used.

The coupling connecting-heads are preferably cast integral with the curved projecting ends having the inclined fiat inner faces and the socket beside the faces corresponding to the curved projection. These connections are so arranged that no matter what end of the car is coupled the connection will register with the abutting connection of the adjacent car. All the parts are interchangeable, so that when any part becomes disarranged a new one may be substituted.

It is evident that various changes and modifications might be madein the form and arrangement of the parts described without departing from the spirit and scope of my invention; hence I do not wish to limit myself to the precise construction herein set forth.
